The design of the VCU outdoor series allows servicing to be carried out readily and easily. The removal of
the top side, front and back panel make almost every part accessible.
Under normal circumstances, these outdoor units only require a check and cleaning of air intake coil surface
once quarterly. However, if a unit is installed in areas subjected to much oil mist and dust, the coils must be
regularly cleaned by qualified Air Conditioner Service Technicians to ensure sufficient heat exchange and
proper operation. Otherwise, the systems life span may be shortened.
CAUTION!
Do not charge OXYGEN, ACETYLENE OR OTHER FLAMMABLE and poisonous gases into the unit
when performing a leakage test or an airtight test. These gases could cause severe explosion and
damage if exposed to high temperature and pressure.
It is recommended that only nitrogen or refrigerant be charged when performing the leakage or airtight
test.
